The Vaskan sector is a region of space in the Delta Quadrant. In 2374, the USS Voyager landed on a Y-class planetoid in the Vaskan sector to replenish its deuterium supplies, where it encountered a bio-mimetic life-form. (VOY: "Course: Oblivion")
- Presumably named for the home system of the Vaskans and the Kyrians, visited by Voyager in "Living Witness", shortly before the events of "Demon".
